This invention relates to machines Vfor slicing meat and other substances. p

Slicing machines have previously been proposed in the operation of whichthe substance to be sliced ispmounted on a rotary table and is carried thereby recurrently past a slicing knife rotating about a stationary axis. The flywheel effect ofthe rotary table renders thev machine particularly easy to operate. Moreover, the rotary table may, if desired, be so constructed that several different pieces of substance can be clamped thereon. Slicing machines have also been proposed in which the substance-carrying table is arrangedy to oscillate through a comparatively` small angle, such machines being particularly convenientwhere a small .pieceof substance has to be quickly cut `into slices.

rEhe object of this invention is to` provide a machine possessing the advantages of both of the above kinds of machines. Y

In accordance with the invention, the slicing machine comprisesa table which iscapable of being either rotated or oscillated, as desired, past the slicing knife of the machine.

A carrier may bepivotally mounted on the stationary frame of the machine, and table may be rotatably mounted on the carrier, means being provided for rotating the table while the carrier is maintained stationary, or for oscillating the carrier while the table is fixed thereon.

In order that the invention may be clearly understood, one embodiment thereof, chosen by way of example, will now be described with reference to the accompanying drawing, whereon z-e Fig. 1 is a view of a slicing machine constructed in accordance with theV invention, the machinebeing shown partly in elevation .and partly in section;

Fig. 2 is a plan of the machine,

with parts thereof broken away;

Fig. 3 is a fragmentary elevation, the view being in the direction of the arrow VHI in Fig. 2.

rlhe stationary frame ofy the slicing machine shown in the drawing-comprises abase 1 and an upright bracket 2 mounted thereon,

the

cured te theshafts 5 an d6 and the gear wheel 8 being secured to a shaft 10, anda chain drive 11 between the counter-,shaft 6 and the knife shaft 12. The shaft 10 eXtendsverti--l cally upwards through the base 1 and acts as a pivot to a carrier 13, whichA isborne lby wheels 14 riding on the base 1. A material supporting member in the form of a circular table 15 is centred on a pivot-pin 16 u'pstanding` from thecarrier 13.

ylf'he table 15 would be provided with known means for clamping on it several different pieces of substance tobe sliced byv the knife 3. ln the construction shown, four independent clamping means would be provided and would be associated kwith automatic mechanism, forming no part of the present invention, for feeding all or any of the pieces ofL substance intermittently towards the knife in the working of the. machine. It is to be understood that simply one clamping means, or other number thereof, might be provided. The clamping means are indicated 'conventionally in the drawing by the chain dotted lines 17.

The table 15 has an internally toothed rim 15 into or out of mesh with which a pinion 18 can be moved. The pinion 18 is slidably mounted on the shaft 10, but is not rotatable relatively. thereto, and can be shifted into or outkof mesh with a spur wheel 19 secured to the upper end of a short crankshaft 2O journaled in, and passing through, the carrier 13. rlhe crankshaft 20, at its lower end, has a crank 21 and crankpin 22, which latter is pinjointed to one end of a connecting rod 23 anchored at its other end to a pin 24 on the base 1. Y

llt will be apparent that, if the pinion 18 were rotated, (as .it will be whenever the flywheel 4 is rotated) while in mesh with the toothed rim 15', the table 15 would rotate, but, if' thepnon 18 were rotated While in a counter-shaft '6,

bracket Z and has a driving connection with rnl f the pinion 18.

mesh -With the spul-Wheel 19, the carrier 13 would be oscillated about the ,shaft 10, by the crank 21 and rod 23. A K

A handlever 25 is provided for controlling The hand lever 25 is 'fulcrumed, at 26, on the carrier 13 and has a project-ion 27 which enters a groove'28in the boss of the pinion. When the handle 29 of the hand. lever 25 occupies its lower position (in which it is shown in the drawing) the pinion 18 is raised into mesh With the toothed rim and the handle is positioned between the arms of the locking member 30. lith the hand lever so positioned, the carrier 13 would be effectively locked to the base 1 by the-locking member 30, so that, if the flywheel l were rotated, the table 15 would rotate continuously about stationary axis, viz. the axis of the pivot-pin hand, when the handle 29 is raised, the hand lever 25 will engage in a notch 31 in the rim 15 (see ldig.V 3), While the pinion 18 Will mesh with the spurwheel 19. The carrier 13 will not now be `locked to the ba se 1, but will be locked instead to the table 15, so that, if the flywheel 4.- vr'ere rotatedthe carrier 13 and the table 15 would oscillate inunison about the anis of the shaft 10.

Four notches 31, displaced aty angles of ninety degrees from one another, would be formed in the rim 15', so that any selected clamping means 17 could be brought into operativerelationship with the knife 3 by adiusting the table 15 on the carrier 13.

Other changes in details of construction Will readily occur to those yskilled in the art and may se made Without departing from the scope of the invention.
